Hi Brian,

Nice pics.... Nice Job....

I like that belt tensioner for the blower! Are you going to hook the OTR Air back up?

Thanks Nick!

Yes, I have the pulley for the OTR Air, just haven't welded it on yet. I also still have to fabricate the tensioner for the belts. I have to figure out some interference issues with the OTR Air AC hoses and the intercooler hoses.

Great job and great pictures! So you have both radiators with two air to air intercoolers in front of each radiator? Greyhound would take one of the radiators out and just use one air to air in its' place with their Series 50 replacements. But perhaps the M11 will produce more heat-nothing wrong with the way you did it though! This is proof positive of the fact that the Cummins M11/ISM is MUCH smaller than the Detroit Diesel Series 60. As much as I like the Series 60, the M11 makes the most sense to me for a replacement bus engine. And with the Autoshift, you'll probably get 8-10mpg easily! Good job! Good Luck, TomC

Wow, very nice, Brian. Yeah, I too am amazed at how much room you still have back there with the engine in place.

I know you told me when I was there, but what's the weight difference between the old 6V92/ Allison vs. the ISM/Autoshift?

Great job,
Brian B.

Hi Brian, I cannot imagine what you must feel like after accomplishing what you did, a major undertaking. So good that you shared the story with pictures, also a good way to document what you did. Good luck with the rest of your project, I am sure it will take you many miles down the road safely.

Happy Trails,

Paul

Brian, I think I estimated 400lbs lighter with the ISM/Autoshift than with the old combo. Most of the weight savings comes on the tranny side as the 6v92 and ISM with wet weights are within 100lbs of each other. However, my weight moment arm on the back of the bus is much better since the weight is moved towards the rear axle by over 2'!

Wow, wish i had the skills to do something like that.. Good on ya dude.. Great job fabing all the fittings too.. I used to be a Welder fabricater, so i know good work when i see it. Would like to see more pics of the mods you did to get it in there right.
Also, in that first shot , it looks like a Garage in there , its so roomy.. you could install a couple of bunk beds for smuggling Aliens in
